The Study of Heat Flux Measurement for Heat Transfer during Condensation at Pipe Surfaces

Аннотация

For the first time, heat transfer during condensation has been studied using gradient heat flux measurement. The applicability of the new method has been tested on a model of a well-studied object—a circular pipe. The experiments involved heat transfer investigation during condensation of saturated water vapor at the outer and inner surfaces of the pipe. Gradient heat flux measurement is shown to be highly informative, which opens up new prospects for research in the field of heat transfer during phase transformations, has been revealed.
